For the haptic feedback? No, it's a mechanical screw with a physical stop to keep it from turning at the right time. You can see it disassembled here. The sensor may be a hall effect sensor, I don't actually know, but once again, the patent isn't about drift.
Watching that video gave me flashbacks about how much of a pain in the ass these are to disassemble, too, which is why I have several of these with stick drift issues just gathering dust instead of actually repairing them.
